Product Introduction
Neway Double Orifice Air Release Valve – Type A is specifically engineered to release trapped air and protect pipelines in pressurized water systems. Designed with dual-function orifices, this automatic air valve efficiently vents accumulated air during normal operation and rapidly admits air during negative pressure conditions, preventing pipeline collapse, deformation, or cracking during events like pump shutdowns or power failures.
The valve's large air discharge capacity and fast air intake response help maintain optimal water flow, enhance hydraulic efficiency, and extend the lifespan of the pipeline infrastructure. Its high-performance design ensures reliable operation in sealed pipeline segments and at high elevation points, where air accumulation or vacuum conditions are most likely to occur.
Ideal for potable water distribution networks, transmission pipelines, irrigation systems, and wastewater applications, the Neway double orifice air release valve provides durable, maintenance-friendly performance in a compact, efficient form
